GTEM CELL 250F FROM GTEM ITALIA

The GTEM 250 F (F for Ferrite tiles) Family from GTEM Italia are designed for testing to IEC/EN 61000-4-20, SAE J1752/3, IEC 62132-2 and IEC 61967-2.

The GTEM 250 F Family with Ferrite tiles on the bottom offers a wider operating bandwidth with peak smoothed and flat response starting from DC to microwave frequencies.

It is an indispensable tool for researchers and developers engineers!

GTEM Italia GTEM 250 F in Horizontal Orientation

There are four models of the GTEM 250 available:

GTEM 250 A-F	Shipped Assembled. With Ferrite tiles. 8cm / 3,15” Flat or 15cm/6” hybrid pyramid + ferrite tiles
GTEM 250 A-F-V	Shipped Assembled. With Ferrite tiles. Vertical Orientation. 8cm / 3,15” Flat or 15cm/6” hybrid pyramid + ferrite tiles
GTEM 250 A-F-SAE	Shipped Assembled. With Ferrite tiles. With SAE Opt. Includes a special opening to test integrated circuits, dimensions: 80 mm x 80 mm on Approx. 45 mm septum height, closed from a removable panel where are placed the IC under testing. 8cm / 3,15”Flat or 15cm/6” hybrid pyramid +ferrite tiles
GTEM 250 A-F-V-SAE	Shipped Assembled. With Ferrite Tiles. Vertical Orientation. With SAE Opt. Includes a special opening to test integrated circuits, dimensions: 80 mm x 80 mm on Approx. 45 mm septum height, closed from a removable panel where are placed the IC under testing. 8cm / 3,15”Flat or 15cm/6” hybrid pyramid + ferrite tiles

The GTEM cell is, in principle, a tapered coaxial line (offset septum plate), which is terminated by a hybrid combination of discrete resistors and RF absorbers to achieve a 50 Ohm broadband match. It is applied for the Measuring of Emission, Radiated, radio frequency field-immunity test.

The GTEM250 Family utilizes Ferrite tiles on the bottom to provide a wider operating bandwidth with peak smoothed and flat response starting from DC to microwave frequencies.

GTEM 250 A-F-SAE and GTEM 250 A-F-V-SAE
Both of the SAE Models (GTEM 250 A-F-SAE and GTEM 250 A-F-V-SAE E) include a special opening to test integrated circuits.

GTEM Italia GTEM 250 SAE Option

The standards SAE J1752/3 and IEC 61967-2 define a method for measuring the electromagnetic radiation from an integrated circuit (IC). The IC itself is mounted on a test board on a panel that is clamped in the upper face close to the top of the GTEM cell. The test board becomes a part of the cell wall.

A receiver or spectrum analyzer measures the RF emissions emanating from the integrated circuit and impressed onto the septum of the cell. The standard IEC 62132-2 defines the immunity test set-up on integrated circuits tested with a GTEM.

Both the GTEM 250 A-F and GTEM 250 A-F-SAE GTEM Cells can be ordered in a Vertical orientation!!!
Great Space Savings orientation!
